They're more than boots. They're insurance for your ankles. We made the Instigator with a higher, more-supportive cut, then backed it up with the Approach TFX outsole and a waterproof GORE-TEX liner. It has a full-grain leather upper with a scuff-proof toe cap. The 100% waterproof GORE-TEX lining adds ultimate breathing comfort. Lightweight, stable TERRA-FORCE X platform enhances side-support and performance. 200 grams of Thinsulate Ultra insulation trap heat. The triangle-shaped lugs on the Danner Approach TFX outsole improves acceleration, downhill braking and traction.
